MACHINE FOR MAKING WIRE SPRINGS AND COUPLINGS.

SPECIFICATION forming part of Letters Patent No. 482,427, datedSeptember 13, 1892. Application filed May 14, 1892. Serial No. 433,010-(No model.)

To all whom it may concern:

Be it known that I, SEBASTIAN KONZ, a citizen of the United States,residing at Louis ville, in the county of Jeiferson and State ofKentucky, have invented certain new and useful Improvements in Machinesfor Making WVire Springs and Couplings; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as IO will enable others skilled in the art to which it appertainsto make and use the same.

This invention has relation to that class of machines designed to coilwire; and it consists in certain peculiarities in the construction,arrangement, and combination of the several parts, substantially ashereinafter described, and particularly pointed out in the subjoinedclaims. I

The object of the invention is to provide a machine which will becapable of making accurately and rapidly wire springs especially adaptedfor seat-bottoms and spring-couplings that may be used as spring-bottomsfor seats. I attain this object by the mechanism 2 5 illustrated in theaccompanying drawings, in

which- Figure 1 is a perspective view of a machine with a section ofwire in position to be rolled into a spring and a spring-couplerinposition on the die-plate; Fig. 2, a front elevation of a doublescrew-vise used for holding the springwire in position; Fig. 3, aperspective view of the double vise in detail, showing a springcompleted; Fig. 4, a modification of a spring 3 5 used in lounges orsofas, and Fig. 5 a springcoupler used in conjunction with the form ofspring shown in Fig. 4.

Similar letters refer to similar parts throughout the several views.

0 The standard A, with its base a a, the journal-b0x A, the guide a, thearm A and the die-plate A constitute the frame of the machine. In thebox A is journaled the shaft B, the outer end of which is squared toreceive the crank-arm B, provided with a handle h and held in place onthe shaft by the pin 17 A groove is sunk around the journal of theshaft, and a screw a fitted in a threaded hole through the journal-box,projects into the groove and prevents the shaft from slipping.

The portion of the shaft on the side of the journal-box A opposite thecrank-arm B is square and designed to carry the double screw-vise C.This vise consists of a base D, having the longitudinal opening throughit square in cross-section and adapted to fit over the square portion ofthe shaft B, two side plates or jaw-pieces d, rectangular in shape,rising perpendicularly from the base D at a suitable distance apart andparallel to each other, a cross-head or top jaw E of a widthsufficientto cover the jaw-pieces d and having guide-pieces e projectingdownward from it within and parallel to the jaw-pieces (Z, a clamp-screwF, which passes through the cross-head E and engages a threaded seat inthe base D, and the sleeves D, projecting horizontally from the sideplates (Z. This clamp-screw is surrounded between the crosshead and thebase by a coil-spring f, which assists in throwing the cross-head upwhen the screw is loosened.

Along the tops of the jaw pieces 01 are grooves d, adapted to receivethe end portions of the wire to be coiled. The openings through thesleeves D are similar in shape to and'register with the opening throughthe base D. Said sleeves are of less diameter than said base, and theshoulders between said base and sleeves are inclined or sloped towardthe latter.

In the outer end of the arm A is a screwthreaded hole, into which isscrewed on the side of the arm opposite the crank end of the shaft thethreaded end of a stud-post a which projects parallel to the shaft. 1.Over this stud-pin is fitted a roller-sleeve G',provided withguiding-beads g. l."

H in Fig. 1 represents a sectionof springsteel wire in position to beworked into a 1 0 double coiled and curved spring and in Fig.

3 shows the same wire in the shape of a complete spring.

K represents a coiled spring with a single curved arm and a loop 70 atits outer end, be- 5 ing a modification of my spring adapted for use inlounges and sofas.

L representsa coupling to be used with the springs K or with the doublespringsin elongated seats.

lVhen my machine is in use, it should be attached to some firmfoundation by bolts or screws passing through the base a a, as indicatedin Fig. 1. The mode of operating it is as follows: A piece ofspring-wire H of sufficient length to make a double coiled and curvedspring of the size desired is bent in the middle and the two endsbrought sufficiently near together that one may fit in the groove in thetop of one of the jaw-pieces d of the vise and the other in the other.In placing the wire ends in the vise the shaft is turned so that theprojecting loop of the wire will be beneath the roller-sleeve G. Thecrank is then turned so as to bring the wire against the roller-sleeve.As the vise turns with the shaft the wire is first bent at right anglesover the upper corners of the jawpieces, then passes straight along thefront edges of the jaw-pieces till it reaches their base, when the slopeof the base-piece from the central portion to the sleeves directs itoutward and coilsit as the shaft turns around the sleeves. The operatorin this process turns thecrank with his right hand and with his leftgrasps the projecting wire arms in the loop and by means of theguide-beads g on the roller-sleeve sees that the coils wrap around thesleeves side by side and are not superimposed. By loosening thevise-screw and sliding the vise off the shaftthe completed spring can bereadily taken off the vise and another piece of wireiuserted. The guidea on the journal-box assists the operator to determine when the lastcoil has been carried far enough and when the projecting loop has thenecessary curve. After the springs are removed from the vise the rightangle made by bending the wire over the upper corners of the vise-jawscan be made sharper by the hammer, or, preferably, after the ends ofwire intended for a spring have been brought into proper juxtapositionthey can be thrust into holes in a plate prepared for the purpose, thewire bent over to a right angle,and the angle squared by the hammer.Then the wire when its ends are placed in the vise will extend directlyalong the straight edges of the jaw-faces, ready to begin coiling aroundthe outer parts of the base-plate as soon as the shaft is turned. Thesingle spring K shown in Fig. 4 is made in the same way, except that itis not doubled, and the loop K on the outer end of it may be formedround the die-plate A with hammer and tweezers. The coupling L is made,preferably, of a piece of spring-wire flattened and then formed on thedie-plate A Having thus described my machine, wha I claim as new, anddesire to secure by Letters Patent, is-

1. In a machine for making wire springs, a double screw-vise having asleeve-base with an opening through it square in cross-section, adaptedto slip over a squared shaft, two jawpieces rectangular as to theirsides and top rising perpendicularly from the base in parallel planes,each provided with a groove along its top edge, and a top jaw orcross-head covering the tops of the base jaw-pieces and provided withtwo downwardly-projecting parallel guide-plates fitting inside and closeto the base jaw-pieces, in combination with a vise-clamping screwpassing perpendicularly through the cross-head or top jaw into ascrewthreaded hole in the sleeve-base and having a coil-springsurrounding its shaft between the top jaw and base, substantially asdescribed.

2. A machine for making wire springs and couplings, having a frameconsisting of a standard A, base a a, journal-box A, arm A guide a anddie-plate A and a stud-post a projecting horizontally from the innerface of the arm A carrying a sleeve-roller G, provided withguide-beadings g, in combination with a shaft B, journaled in the box A,provided with a crank and handle at its outer end, and having its innerend squared and carrying a double screw-vise O, constructed and arrangedsubstantially as set forth, and for the purposes specified.

3. The combination, with the frame, the shaft journaled therein, andmeans for rotating said shaft, of a vise secured to said shaft androtating therewith, said vise having a grooved top and sloping bottom,and sleeves projecting from said vise and adjacent to the sloping bottomthereof,substantiallyas shown and described.

4:. The combination, with the frame, the shaft journaled therein, meansfor rotating said shaft, and the I roller-sleeve G, having beads g g, ofa vise located adjacent to said sleeve and rotatable with said shaft,said vise havinga grooved top and sloping bottom, and sleeves projectingfrom said sloping bottom of the vise.

5. The combination, with the vise consisting of a base, two side jaws, aremovable top jaw, and sleeves projecting laterally from said side jaws,said side jaws having their tops grooved and their bottoms sloped towardsaid sleeves, a clamping-screw engaging said top jaw and the base of thevise, and a coil-spring encircling said screw, of a supporting-frame andmeans for rotating said vise.

In testimony whereof I affix my signature in presence of two witnesses.
